lthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in gang-disk cultivators; and it consists in, first,

a gang of three or more disks secured to a pivoted yoke which is capable of being adjusted so as to move the disks near together or far apart, and which disks are adapted to be turned at any desired angle, second, the combination of the standard provided with two holes in its lower end, the hub pivoted upon the standard and held in position by means of a wooden break-pin which can be ad# justed from one hole to another, so as to cause the disk to stand at any desired angle, and a hollow lubricating-axle which is provided with a cap-plate at one end and has the disk secured to the other, and which axle in revolving in the hub keeps it constantly lubricated, third, in the arrangement and combinationof devices which will be more fully described hereinafter.

In the accompanying drawings, Figure l is a rear view of a cultivator embodying my invention. Figs. 2, 3, 4, 5, 6, and 7 are detail views of different parts. Fig. 8 is a plan view of the beams detached froml the cultivator and showing the manner of attachment of the different parts. Fig. 9 is a rear View of the parts shown in Fig. 8. Fig. lO is a side view of one 0f the beams and the parts attached thereto.

A represents the axle and B the wheels.

` The beams consist of the two long `beams O and the two shorter ones D, which are secured at their front ends to the longer ones, as shown in Fig. 8. Double beams are used, as shown, for the purpose of forming solid supports for the operating parts connected thereto. The

rear ends of these beams are connected by means of the flanged plates F, which may either be applied to the tops of the beams, as shown in Fig. 1, and bolted in position, or the plates may be formed as shown in Figs. 8 and 9 and applied to the under sides of the beams, as shown. If constructed as shown in Figs. 8 and 9, these plates F are provided with narrow ianges G, which catch over the top edges of the beams, and thus do away with the necessity of using the bolts H. (Shown in Fig. l.) Each of the plates F is provided with a central opening I and two curved slots J, as shown fully in Figs. 7 and 8. The arch K, shaped as shown in Fig. l, has its ends secured to the rear ends of the beams and to the plates F by means of the ciamping -bolts L, which are more particularly shown in Fig. 10, and which bolts also serve to secure the right angled pivotal plates N, which, in addition to having openings through their tops for the bolts L to pass through, are provided with the circular slots O near their upper ends and the boltholes P in their'lower ends, as shown in Fig. 6. If the platesl F are formed as shown in Fig. l, these pivoted platesN are applied directly to the under sides of the plates in between the rear ends of the beams; but if the plates are formed and applied as shown in Fig. 9 the plates N are applied to the under sides of the plates F below the beams. Pivoted to the lower end of this plate N by means of the bolt Q (shown in dotted lines in Fig. 9) is the yoke R, provided with the slot S, through which and the slot O passes the clamping-bolt T, by which the yoke is held at any desired angle.' As the plate F is provided with the ytwo circular slots J, and as the top portion of the plate N is provided with two correspondingholes U, through which the clamping-bolts V are passed, itwill readily be seen that the plate N can be turned at any desired angle to the beams upon its pivotal bolt L, and then securely clamped in position by the two bolts V. This adjustment of the plate N causes the yoke R to stand at any desired angle to the beams for the purpose of regulating the angle that the disks W shall stand to the forward line of motion. By adjusting the yokes R upon their pivots Q the distance between the gangs is regulated. Through the yoke are formed suitable sockets X to receive the upper ends of the standards Y, which standards are round at their upper ends and can be turned freely in their sockets, and then secured in position by means of suitable clamproc ing-bolts. These standards being round at their upper ends, the disks can be set at any desired angle to the forward line of motion.

The lower end of each standard Y is curved or bent and provided with two openings, through the lower one of which passes the pivotal bolt Z and through the upper one the pin A', by means of which the disks are regulated in regard to the angle at which they shall stand to the standards. The pin A is made of wood and is intended to break in case any one of the disks should strike an obstruction. Each disk is provided with a sleeve B', which has the extension C' extending from its top and which extension corresponds to the lower bent portion of the standard, as shown in Fig. et. Through this sleeve is formed an opening through which the pivotal bolt Z passes, and through its upper end are made three or more holes through which the break-pin A is passed. Each disk is secured to one end of a hollow axle D by means of a bolt F, which passes through the axle. One end of the axle is provided with a flange G', which catches against or over one end of the sleeve, and then the disk bears against the opposite end and is secured to the end of the axle by a washer I. The axle is hollow and provided with an opening near its center, through which the lubricant with which it is filled is fed to the sleeve, so as to keep each axle constantly lubricated.

From the above description it will be seen that each gang of disks consists of but very few parts which are not liable to get out of order, and that every possible adjustment necessary can be given to the disks. Each gang is provided with suitable braces, as shown in Fig. l, and they are designed to be raised and lowered by the levers mounted upon the axle in the usual manner. These gangs cultivate in the middle of the rows; but l l g l "l li pose there is clamped to the top of each pair of beams a casting L by means of screw-hook bolts, which pass through slots in the casting, as shown in Fig. 8. These castings L are adjustable endwise baek and forth across the tops of the beams C D, so as to bring the disks in any desired relation to each other. These disks are arranged, as shown, in advance of the gangs of disks, and the distance in advance can be regulated at will by simply loosening the hooked bolts and sliding the casting L either forward or ba'ck. As here shown, the single disks overlap the front edges of the gangs of disks; but this is matter of choice. These single disks can be given every adjustment of the disks in the gangs.

Having thus described my invention, I claim- 1. The standards, the sleeves pivoted thereon, the hollow axles passing through the sleeves, and the disks secured to the ends of the sleeves, substantially as set forth.

2. The standards, the sleeves adjustably pivoted thereon, and the hollow axles passing through the ends of the sleeves, combined y with the clamping bolts which pass through the axle, the disks, and the washers, substantially as specified.

3. The beams, the flanged plate or casting F, secured thereto, and provided with slots, the angular plate or casting N bolted to the under side of the casting F, and the yoke pivoted to the plate or casting N, and provided with a series of disks, substantially as shown.

4. The pivoted slotted yoke and the standards carrying disks, combined with an angular plate upon which the yoke is pivoted, and which plate is clamped to the beams and adapted to be turned upon its pivot carrying the yoke with it, substantially as described.

In testimony whereof I have ailixed my signature in presence of two Witnesses.
